This work was the first in Spain to deal specifically and completely with thoroughbass accompaniment at the keyboard. This bilingual edition presents a readily legible transcription of the full Spanish text of the 1736 edition and with the original pagination. The Reglas Generales were first published in 1702 by Jose de Torres's own print shop in Madrid, and a second edition appeared in 1736. This work was the first in Spain to deal specifically and completely with thoroughbass accompaniment at the keyboard. Also a pioneering work for its treatment of what Torres describes as the rigorous Spanish style," this treatise approaches thoroughbass from a contrapuntal as well as a harmonic perspective. Unlike the writers of guitar treatises of the same period, Torres considers chord inversion and voice leading in the realisation of the bass. This bilingual edition presents a readily legible transcription of the full Spanish text of the 1736 edition and with the original pagination with the English translation facing the original, the reader can easily move between the Spanish and English versions. Musical examples are given in facsimile with the Spanish text and in modern notation in the translation. Annotations to the translation are easily located, yet unobtrusive."
